It's Steve Carell's last episode of Scranton-set show "The Office" this Thursday. He'll sign off as boss of the Scranton branch of Dunder Mifflin in a 50-minute episode at 9 p.m. on NBC.

A slew of guest stars - including Ray Ramano, James Spader, British comedienne and "Doctor Who" alum Catherine Tate, Ricky Gervais, Will Ferrell and Will Arnett - will appear in the May 19 finale, so Michael's replacement is still up in the air.

It's hard to capture the magic of Michael Scott in words, so we're going to the always-reliable land of YouTube for tributes to the boss.
